Schematic presentation of cuboid-shaped crystallites on a substrate with (a) no preferred orientation and (b) uniplanar texture with a defined preferred orientation of a crystallographic lattice plane parallel to the substrate. The sphere of crystallite orientations shows (c) constant pole density for a powder and (d) concentric rings of enhanced pole density for a uniplanar texture, corresponding to an uneven distribution of crystallite orientations. The same behavior is observed in radial intensity profiles showing the pole density as a function of the polar angle ψ for (e) powder and (f) uniplanar texture. The indicated full width at half-maximum (FWHM) describes the out-of-plane mosaicity of a uniplanar texture.
